LUBRICATOR.

Application filed Ju1y 3,

This inventionrelates to improvements in lubricators.

An object of the invention is to provide mechanism for lubricating the tire flanges of railway car or locomotive wheels, to reduce the rapid wear occurrring in service due to the excessive friction between unlubricated surfaces, said mechanism being arranged to operate automatically to feed lubricant to the wheels when the same are in motion, and to cut off the feed when the wheels are at rest.

Another object of the invention is to provide a mechanism of this character in which the feeding means include an actuating ele ment associated with a reservoir containing lubricant, and co-operating with a flanged wheel, whereby the vibration of the wheel during its travel imparts vibratory movement to said actuating element which operates valve means to release small quantities of lubricant upon the wheel, the arrangement being such that when the actuating element is no longer vibrated as when the wheel comes to rest, the flow of lubricant is automatically checked.

Another object ot'the invention is to prvide a mechanism in which novel means are utilized for maintaining the mechanism in position to be acted upon by the movement of the wheel with which it is associated, said means being arranged to yieldably maintain the mechanism in operative relation with the wheel in the plane of its movement, and also in operative relation with the flange oi the wheel at an angleto the plane of the movement of said wheel.

Other and further objects of the invention will more fully and clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specification, Figure 1 is a fragmentary side elevation of a locomotive showing my invention in connection therewith; Figure 2 is a transverse vertical sectional view on the line 2-2 oi? Figure 1; Figure 3 is an enlarged vertical sectional view through the lubricating device proper, and through the wheel with which it co operates; and. Figure at a transverse sectional view of the in vention on the line ll of Figure 8.

Itet'erringmore particularly to the drawings, the invention is illustrated as applied toa locomotive, though it is obvious that 1925. Serial No. 41,239.

the device may be used in connection with any other vehicle provided with wheels, and 111 connection with which it is desired to lubricate the tires thereof.

As shown in the drawings, denotes the boiler of the locomotive, 11 cross-brace or guide arms, 12 a gusset plate, 13 the frame, 14: an axle, and 15 the wheels, said wheels being provided with the usual flanges 16 which bear upon the inner sides of the track 17.

As shown lubricating means are provided at opposite sides of the locomotive, or other vehicle, each lubricating means being indicated as an entirety at A, and including a tank or reservoir B, and a distributor C The tank or reservoir B on the left side of the locomotive as shown in Figure 2 is mounted on a support 19, connected by suitable n eansto the boiler 10, the end of the support 19 projecting outwardly beyond the cylinder 18 a suitable distance, and secured to the support 19 by means of bolts 20 are spaced straps 21 and 22, such straps being arranged to accommodate the tank 13 associated therewith, a filling pipe and a cap for the tank being provided which projects above the support 19, as shown at 23. The tank B is provided with a conduit 123 of any suitable materiah which leads to the distributor G and is adapted to conduct lubricant thereto, a valve'Qd being inter posed between the ends of the conduit for controlling the passage of lubricant to the distributor. The lubricating means associated with the wheel upon the opposite side of the boiler 10, are identically similar to those just described, except for the provision of a slightly different bracket tor supporting the tank, and the same reference characters will be used to describe similar parts of such construction. The distributors C in both instances are identically simi' lar in construction and operation, and only one of the same willbe described in detail herein. j

Each distributor C isanou'nted upon a supporting arm having a flattened portion 3O by which the arm is secured to an angular bracketBi fastened to the plate or diaphragm 12, said arm 30 projecting out wardly toward the adjacent wheel 15. The other end of the arm 30 is providedwith a bore 32 for the reception of the shank 83 of a T-head 3d, the shank being secured in position by pins 35, the-head of the T member 34 being provided with a socket 365, in which may bedisposed the turned end 37 of a coiled spring 38 which is disposed about the body portion of the arm 30, the inner end of the spring 38 hearing against the inner face of a sleeve 39 which is loosely mounted upon the arm 30. The sleeve 39 includes an enlarged portion 40, providing a socket for the threaded reception of the hollow extension 41 formed on the body portion'42 of the distributor C, the arrangement being such" that the coiled'spring 38 is under torsion when placed in position, as well as under longitudinal compression, whereby the inner end of the spring 38 by engage ment with suitable lugs 43 on the inner face ofthe hollow extension 41 urges the distributor in a clockwise direction, and also by reason of the pressure of the spring upon the sleeve 39, urges the distributor inwardly toward the flange 16 of the'wheel 15, it being noted that the tension exerted by the spring may be regulated when desired by engaging the turned end 138 of the spring 7 provided with a conical valve seat 46, and

co operating with the valve seat is a conical valve 47 forming part of the actuating member 48, said actuating member projecting outwardly through an oil chamber 49, and through the nozzle 50, and into engage ment with the wheel 15, it being noted that the actuating member 48 has a loose lit with the nozzle 50 of the body portion of the distributor, and interposed between the inner end of the actuating member and the inner wall of the nipple 143Kis a coiled spring 51 which normally urges theactuating member 48 to projected position.

In use,the check valve 24 is operated to permit passage of the lubricant to the dis tributor, said lubricant passing into the chamber 42 ,'where the same will remain,

when'thewheels are atrest, due to theengagement of the conical valve with the tapered valve seat of the body portion 42, the

actuating member 48 being held in contact in the plane of movement of the wheelby the torsional pressure afforded by the coiled 'sarin 38 and said actuatin member being pressed inwardly against the flange 16 by means of'the longitudinal pressure exerted by thespring upon the sleeve 39 which is connected to the extension 41 forming part of the distributorC. When the wheel 15 is in motion, due to the vibration thereof during its travel, vibratory move-' ment will be imparted to the actuating member 48, causing the. same to move the valve 47 out of and into contact with the valve seat, thereby releasing a small quantity of lubricant, which initially flows into the chamber 49, and thereafter passes out of the nozzle 50 onto the wheel 15. As soon as the wheel comes to rest,fthe.vibration ceases, permitting the valve associated with the actuating member 48 to remain in contact with the valve seat 46.

With the above described arrangement means are provided for causing the automatic flow of lubricant when the'wheels are in motion, and when the wheels come to rest, to automatically check the flow of lubricant thereto, the'construction being such that the distributor is held in operative en gagenient with the wheel" in two directions by p a simple and convenient arrangement of mechanism.
